Python: Remove the ANSI escape sequences from a string

Python Regular Expression: Exercise-45 with Solution

Write a Python program to remove the ANSI escape sequences from a string.

Sample Solution:-

Python Code:

import re
text = "\t\u001b[0;35mgoogle.com\u001b[0m \u001b[0;36m216.58.218.206\u001b[0m"
print("Original Text: ",text)
reaesc = re.compile(r'\x1b[^m]*m')
new_text = reaesc.sub('', text)
print("New Text: ",new_text)

Sample Output:

Original Text:          google.com 216.58.218.206                                                             
New Text:       google.com 216.58.218.206

Python: Tips of the Day

Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value

Example:

def tips_map_values(obj, fn):
  ret = {}
  for key in obj.keys():
    ret[key] = fn(obj[key])
  return ret
users = {
  'Owen': { 'user': 'Owen', 'age': 29 },
  'Eddie': { 'user': 'Eddie', 'age': 15 }
}

print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}

Output:

{'Owen': 29, 'Eddie': 15}
